Maybe their concept of fuzzing is different?
Jarred commented on the top that they use fuzzilli , which is a javascript engine fuzzer.
But zig has a built in integrated fuzzer!
Andrew must have been talking about the built in fuzzer because that's what is associated with zig.
zig build test --fuzz
The fact that Bun is the face of Zig owes to (1) its popularity in the relatively enormous web ecosystem and (2) that there aren't many winners in Zig. This means Bun leaving and rewriting to Rust, no matter how its phrased by any of the major parties, was always going to be alternatively reframed as one of the few major proponents of Zig leaving for Rust.
That's why this is a PR moment for Zig.
It's not because Jarred was a bad manager, one who overworks his team, a poor communicator, one who doesn't develop intimacy with the internal core team at Zig, an amateur coder, or a liar about whether or not they've been fuzzing.
